BATCH BOX.

Application filed August 20, 1923. Serial No. 658,374.

T 0 all yw hom it may concern Be it known that I, Josemi H. Mosul., a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new und useful Improvements in Batch Boxes, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

This invention relates to batch boxes f'or cement and similar substances, and the object of the invention is to improve the construction and operation of batch boxes in the manner to be hereinafter described and claimed.

Referring to the drawings which accompany this specification and form a part hereof, which drawings illustrate an em bodiment of this invention and on which drawings the same reference characters are used to designate the same parts wherever they may appear in each of the several views, Fig. 1 is a side elevation of a batch box; Fig. 2 is an end elevation of a batch box; and Fig. 3 is a section of the batch box taken on the line 3 3 on Fig. 1, looking in the direction indicated by the arrows.

Referring to the drawings, the reference numeral 1, designates a batch box, which can be constructed in any suitable manner.

The batch box illustrated by the drawings is a sheet metal box, which is illustra-ted as composed of two sheets of metal, 2 and 3,

suitably bent and joined to ther to form the sides and ends of the ox as well as flanges for securing the two sheets of metal together, as will be readily understood from an inspection of Fig. 3 of the drawings, which shows the sheet of' metal 2 bent at right angles at 4 to form. the end 5, and bent again at right angles to form the flange 6 which is secured to the sheet of metal 3; likewise, the sheet of metal 3 is bent at right angles at 7 to form the end 8 and is again bent at right angles to form the flange 9. A bottom, 10, provided with downturned fianges 11, is secured within and to the sides and ends of the box 1. A

brace or stiiening member 12 is secured to the opposite sides of the box to prevent displacement of the sides of the box, either by bulging outwardly, due to the pressure of cement in the box and to prevent the sides of the box from being bent in, or dented, when the box is being emptied and is resting against some kind of a support. The brace or stiffening member 12 is illustrated by the drawings as provided with flanges 13 and 14 which are riveted to the sides of the box, and the brace or stifiening member 12 terminates short of the bottom of the box, for the reason to be presently explained.

The box may be provided with a cover 15 and the cover may be provided with a handle 16.

Cement, and by the word, cement, is meant the ordinary Portland cementI of commerce which is used for building operations, dams, bridges, roads, etc., when prepared for use and hydration is an extremely tine powder, and under certain conditions this powder will cohere and mass together and adhere to batch boxes and similar containers. Such coherence and adherence are apt to occur when batch boxes of cement are transported on industrial railways, for example, to a concrete mixer, due to the shaking and vibration of the cement in the batch boxes as a. result of the jolting which the batch boxes are subjected to while being moved over the track. Dam ness or moisture increases the tendency o the cement to stick to the batch boxes and to stick together, and it is quite frequently necessary topound upon the batch boxes or to jar them, to break away, sav a few inches, of cementwhich has a tendency to stick to the bottoms of the batch boxes.

The principal object of this invention is to provide means, combined with batch boxes, to effectively cause all of the cement to be discharged from the batch boxes without the necessity of pounding or jarring the batch boxes, and this object is attained by Jfastening to the interiors of batch boxes heavy movable members such, for example, as slack chains 17 and 18, which will fall by gravity when the batch boxes are inverted or tipped sufficiently, and in falling will carry with them, break away, and loosen the cement which is compact or which is stuck to the batch boxes.

In the specific construction illustrated by the drawings, the two chains, 17 and 18 extend diagonally across the batch box an are secured to bolts 19, 20, 21, and 22, which are secured to the sides of the box at short distances above the bottom of the box. As clearly shown by Figs. 1 and 2 of the drawings, the chains 17 and 18 are slack enough to permit the majority of the links compos ing the chain to lie loosely on. the bottom of the box and below the brace or stiftening member 12. The slack chains, 17 and 18, constitute heavy movable elements secured in the interior of the batch box to displace material compacted in the batch box.

The operation of the batch box will. be obvious from the foregoing description. When the batch box is inverted or inclined for the discharge of its contents, the slack chains, 17 and 18, will tend to move away from the bottom of the batch box and thereby displace and loosen material which may have become compacted in the bottom of the batch box, or which may have stuck thereto, thereby freeinof the batch box of the material contained1 therein.

What I claim is:

1. The combination with a batch box, provided with a bottom, of a heavy movable element, secured in the interior of the batch box to displace material compacted in, or sticking to, the batch box.

2. The combination with a batch box, provided with a bottom, of a plurality of heavy movable elements, secured in the interior of the batch boX to displace material compacted in, or sticking to, the batch box.

In Witness whereof l hereto affix my signature.

JOSEPH H. MOSEL.
